HANDLE FOR HAIR-CLIPPERS.

SPECIFICATION forming part of Letters Patent No. 793,418, dated June 27, 1905.

Application filed December 30 1902. Serial No. 137,160.

To all whom it may concern.-

Beitknown thatLGEoReE H. OoA'rEs,acitizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Handles for Hair- Clippers, of which the following is a specification accompanied by drawings forming a part of the same.

My present invention relates particularly to the handles and the head of a hair-clipper,

whereby the clipper is rendered lighter and the cost of construction is reduced.

At present the fixed handle of a clipper, together with its enlarged end, known as the head, and the movable handle by which the reciprocating cutting-plate is actuated, are made by casting in metal, usually in malleable iron. By this method these parts require finishing or smoothing to remove the roughness and inequalities of the cast metal. The method of casting and finishing is slow and expensive, and these parts when cast add considerably to the weight of the clipper. By my invention I am enabled to stamp the fixed handle and head of a clipper in asingle piece from sheet metal, thereby obviating the objections to clipper-handles made from cast metal, as the weight of the clipper is reduced and the smoothing and finishing required when cast is avoided.

In the accompanying drawings I have represented so much of a hair-clipper as is necessary to illustrate the nature of my invention.

Figure 1 represents the under side of a fixed handle and head fora hair-clipper made from sheet metal and embodying my invention. Figs. 2 and 3 are perspective and side views of the same.

Similar figures of reference refer to similar parts in the different views.

In my invention the parts comprising the clipper are the same as now in common use, but the fixed handle and head, and also the movable handle, are each stamped from a single piece of sheet metal.

A suitably-shaped blank having been prepared, the fixed handle and head is stamped by appropriate dies into the shape shown in the drawings, in which 1 denotes the handle portion, 2 a projection to receive the thumb, and 3 the head portion. The blank is then twisted at the neck, as shown at 12, to bring the handle 1 into a convenient position for operation. The enlarged dish-shaped head 3 forms a cover for the operating parts, which are inclosed in a recess or chamber 7. This inclosure 7 is completed by two rearwardlyextending wings 1 1 and 15, whose edges 18 and 19 are caused to abut in the finished clipper. This closes the rear side of the head and also forms a support for the cutting-plate of the clipper. By thus forming these wings I am enabled to construct the fixed handle and head from a single blank by stamping, as the wings can be bent up after the stamping is completed. The fixed handle and head having thus been constructed, I stamp from a suitably-shaped blank by appropriate dies a movable handle of any desired form, which may be inserted through an opening 23 into the head of the clipper to engage and operate the cutting mechanism, which is mounted upon a hollow hub 25, inserted in the head. In the opening 24 I can insert the usual torsional spring for reversing the motion of the movable handle. In this manner a clipper is constructed which is distinguished by its lightness and in which the long and costly-process of casting and finishing is entirely done away with.

What I claim as my invention, and desire to secure by Letters Patent, is

1. As an article of manufacture, a handle for a hair-clipper, comprising a section adapted to be seized by the hand and a dish-shaped head having two rearward wings with abutting edges, thereby closing the rear side of the dish shaped head, substantially as described.

2. The fixed handle of a hair-clipper, with a dish-shaped head, having the rear side of said head formed by abutting wings, substantially as described. 7
